A narrow sea passage which separates the eastern tip of Siberia from Alaska and links the Arctic Ocean with the Bering Sea, about 85 km (53 miles) wide at its narrowest point. During the Ice Age, as a result of a drop in sea levels, the Bering land bridge formed between the two continents, allowing the migration of animals and dispersal of plants in both directions.
